Liverpool legend Jamie Carragher says Arsenal need to buy a senior No1.

Carragher doesn't see current stopper David Ospina as the long-term option between the sticks.

Speaking before Arsenal's 1-0 defeat to Swansea, Carragher aired his belief that the Gunners' priority this summer should be to find a bona fide number one goalkeeper.

"I think Arsenal need to go out in the summer and just buy a proper No. 1," he said on Monday Night Football.

"That's what Arsenal need. They need a world-class goalkeeper. Petr Cech? I don't think Jose would like that."
